WAGON-AXLE.

Specification of Letters Patent.

Patented May 27 1913.

Application filed. January 21, 1911. Serial No. 603,855.

To all whom it may concern:

Be it known that I, HANS SUNDBY, a citizen of the United States ofAmerica, residing at Stoughton, in the county of Dane and State ofWisconsin, have invented certain new and useful Improvements inWagon-Axles, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to certain new and useful improvements in wagonaxles, and relates more particularly to that type of wagon axle in whichthimble skeins are employed, and has for its principal object to providemeans for strengthening the axle and skein at the point where thegreatest liability for breakage occurs.

The invention has for its further object to provide means for securingthe trussbar in such a manner as to better support the axle.

Still further objects are to provide a construction simple and durablein its nature, effective for the purposes for which it is designed, andcomparatively inexpensive to manufacture.

The invention consists in the novel construction, combination andarrangement of parts as will be hereinafter specifically described, andthen claimed, and in describing the invention in detail, reference willbe had to the accompanying drawing forming a part of this specification,wherein like numerals of reference will be employed for indicating likeparts throughout the several views of the drawing, in which Figure 1 isa sectional side elevation of a portion of an axle, constructed inaccordance with my invention. Fig. 2 is an underneath plan View of thesame. Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 1. Fig.4: is a similar view taken through the line 4-4 of Fig. 1, and, Fig. 5is a plan and edge view of the truss-bar partly broken away.

In the drawings, 10 designates the axle, provided at each end (only oneend being shown) with the usual tapering spindle portion 11. Thisspindle portion is provided throughout its length with a central slot 12which extends some distance into the body of the axle at the inner endof the spindle portion. In this slot is fitted a strengthening-plate 14,completely filling said slot and shaped to conform to the axle andspindleportion of the latter. Said plate is provided on its upper edgewith a shoulder 15 and with a notch or seat 16, and on its outer end hasa threaded shank 17 to receive a nut 18. On its lower edge, adjacent itsinner end, the plate has two spaced lugs or projections 22, the purposeof which will presently appear. On the spindle-portion 11 is fitted theskein 19, provided with sand-collars 20 and 21 respectively. The wheel(not shown) is held on the skein by a nut 23. The upper edge of theplate 14 is flush with the upper face of the axle 10, and the seat 16 insaid plate registers with the usual seat made in the axle for the hound24, on which the bolster 25 rests, the parts being secured by a clip orclevis 26, which spans the bolster, and has its two arms passed throughthe hound and spanning or straddling the axle, said arms being providedwith threaded extremities to receive securing nuts 27 These arms passthrough a hound-brace 28, and a cross-bar 29 underlying the said braceand are secured by the aforesaid nuts 27. A truss-bar 30 extendslongitudinally of the axle, underneath the same and lies between thebrace 28 and bar 29, extending from one skein to the other, the bar 29being shaped (see Fig. 3) so that the truss-bar may be received betweensaid bar and the houndbrace. The truss-bar 30 is provided with openings31 to receive the lugs or projections 22 on the lower edge of thestrengthening plate 14, said lugs or projections spanning the brace 28and the bar 29 as shown in Figs. 1 and 2. The said collar 21 isperipherally grooved to receive a clevis 32, the arms of which pass downon opposite sides of the skein and through a cross-bar 33 and alsothrough a hound-brace 34 running from the front hound to the skein 19,the clevis being held by nuts 35 on the threaded ends of the arms. Thebar 33 is preferably formed on one end with a hook 36 which receives oneend of the stay-chains that connect with the eveners (not shown). Thetruss-bar has its end held by the bar 33 and hound-brace 34:, the saidend being turned downwardly as at 37 to engage one side of said bar 33.

It is a well known fact that axles are subjected to the greatest strain,and most liable to breakage at a point between the sand collar 20 andthe end of the major portion or body of the axle. By extending thestrengthening plate throughout the length of the spindle-portion of theaxle and for some distance into the body of the latter, the axle isefiectually strengthened at its Weakest point. The manner of securingthe plate in position by the seating of the hound therein,and the lugsengaging in the trussbar effectually holds same and prevents anyindependent movement of the plate; the plate is easily applied,necessitating merely the slotting of the axle from the outer end of thespindle-portion inwardly into the axle the desired distance.

\Vhat I claim is:

A device of the class described comprising an axle having a spindleprovided With a vertical slot extending centrally the length of thespindle With the slot extending into the body of the axle, a skeinmounted upon said spindle, a strengthening plate fitted in and of thesame length as said slot, the upper and loWer edges of said plate beingflush with the periphery of the spindle and axle for the entire lengthof the said slotted portion, a shoulder upon the upper edge of the plateagainst Which the inner end of the skein abuts, means for securing theskein against said shoulder and against the outer end of said plate,said plate notched in its upper edge to form a seat for a hound, lugscarried by the lower edge of the plate adjacent its inner end anddepending below the body of the axle, a truss-bar underlying the axleand having openings receiving the lugs of said plate, means for securingthe outer end of the truss-bar to the skein securing means whereby thetruss-bar also acts to secure the skein on the spindle, a cross-barextending between the lugs and engaging the trussbar, and means forsecuring the cross-bar to the axle.

n testimony whereof I aflix my signature in the presence of twoWitnesses.

HANS SUN DBY.
